SPECIFICATION forming part of Letters Patent No. 498,696, dated 30, 1893.

Application led December 10, 1892. Serial No. 454,713. (No model.)

To all whom it mag/concern:

Be it known that I, ALBERT G. PROVINE, of Puyallup, in the county of Pierce and State of Washington, have invented a new and Improved Sprayer, of which thel following is a full, clear, and exact description.

The-'object of the invention is to provide a.

new and improved sprayer, Whichis simple and durablein construction, very effect-ive in operation, and more especially designed for Ispraying vines, trees, and other lvegetable growth, with a prepared liquid solution for thepurpose of insect pests.

The invention consists of certainparts and details, and combinations of the same, as lwill be hereinafter described and then pointed out' in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts'in -all the figures.

Figure l is a perspective view of the improvement. Fig. 2 is a reduced plan view of the same. Fig. 3 is an enlarged 'transverse'v section of the same on the line 3 3 of Fig. 2. Fig. 4 is a sectional plan view of part of the discharge pipe; and Fig. 5 is a sectional side elevation of part of the'improvement on the.

line 5-5 of Fig. 2. t

The improved sprayer is provided with a suitably constructed frame A, in which is journaled a hollow roller B, forming the liquid supply vessel and at the same time forming the means for actuating the pumps to draw the liquid'from thesaid vessel and to force it into Vthe spraying nozzles, as hereinafter more fully described.

The frame A is provided with a forward extension C, supported on a guide wheel D, journaled in a frame attached to the drive beam E, pivotally-connected with the extension C, as plainly illustrated in Figs. 2 and 5, so that when the draft beam E is pulled to one side, the wheel D moves in like direction to move the sprayer around groves, or turning the same at the end of the row. In one end of the hollow roller Bis arranged a filling pipe F through which the liquid is introduced c xterminating or destroying both made hollow andthrough the axle B extends a pipe Gto permit airto 'pass from the outside into the interior of the hollow roller The axles B' and B2V for the roller B are B to insure an easy .working ofv ythe pumps,

the said pipe G extending with its inner end close to the top of the roller B, as illustrated f of the latter is connected with one or morepumps I of any approved construction, and

supported on the frameA, asl plainly shown in Fig. l.

The piston rods ofthe pumps I are connected by pitman I with crank arms'J of a main shaft J extending transversely onlthe front end of theframe A and journaled in suitable bearings attached to the frame. VAOn the shaft J is secured a sprocketwheel J Zover which passes a sprocket chain J 3 also passing over a sprocket wheel B4 formed on the axle B or otherwise secured to one end of the ro1ler`B, so that when theflatte'r rolls off on the ground on the forward or backward movement of the machine, a traveling motion'is given to the sprocket chain J3, wherebv the main shaft J is rotated andthe crank arins J actuate the pump pistons so as to draw in l through the pipe H, liquid from the roller B.

The sprocket chain J B is engaged by a, tight. ening roller J 4 held on the frarneA to take up any slack in the said chain.

The pumps I are provided With'a discharge pipe K leading to alongitudinally-extending pipe K carrying an air reservoir K2 and provided at one end with a safety valve K3 of any approved construction. A cock K4 is also held in the said pipe K to close the latter whenever desired. The forward end'of the pipe K connects with a transversely-extendingpipe K5 provided at each end with a stuifing box K6 engaged by an extension pipe L mounted to slide transversely in said pipe K5 and stuffing box K6 and connected at its outer end with a vertically disposed pipe L supported on the respective side of the main frame A, as plainly shown in Fig. l. By this arrangement the pipes L can be moved nearer IOO kIO

zles O, so that when the pumps I are working,

the liquid is forced through the pipes K, K',

K5, L and N through the said spraying nozzles O to spray the vines, trees, or other Vegetable growth located at the sides of the machine.

Each of the vertical pipes L is additionally supported by a pipe P and braces Q extending from the pipe P to the pipe L.- Each pipe P is fitted to slide transversely in the frame A and is adapted to be secured thereto by a screw P', screwing in the frame.

When the roller Bis filled with the liquid to be spray ed and the machine is moved forward over'the field, then the roller B rolls off on the ground and by the: mechanism above de.

scribed, actuates the pumps I, so lthat the latter rdraw the liquid from the rollerB and force thesame through the various pipes to the nozzles O-which spray the liquid onto'the vines at the sides of the machine, it being understood that the machine is passed through a row of vines in the field. In order to connect the driving shaft J to, and disconnect the saine from the wheel J 2, I mount the latter loosely on the shaft J on which is mounted .to turn and to slide, a clutch adapted to be thrown in engagement with the clutch teeth on the hub of the wheel J2. This clutch R is engaged by a shifting lever S under the control of the operator, so that the latter `can at any time throw the pump actuating mechanism out of mesh to stop spraying while the machine is passed over the ground.

It is understood that the outer end of the pipe G is secured to the frame A so that the upper inner end of the pipe always extends to the top of the roller B, as shownin Fig. 3. It is further understood that when the machine is in action, the roller B serves as an agitator for the liquid so that the latter is continually stirred up and hencenot liable to settle. v Y Y Having thus fully described my invention, I claim as new, and desire to secure by Letters Patenty l. A sprayer comprising a frame, a hollow tank forming roller journaled in the frame, a pumping mechanism mounted on the frame, and connected with the interior of the roller,

vertically extending pipes L at the' sides of the frame and connected with the pump out lets, and the longitudinally extending series of pipes N extending from the pipes L one' above the other along the sidesof. Vthe frame and each'provid'ed with a series'of spraying nozzles, substantially as set forth. v

2. The combination Witlrthe frame the `roller'tank andthe pumping mechanism connected therewith of atransverse pipe K5 connected with the pump outlets packing glands at the ends of the said pipe laterally adjust-- able pipes lL having transverse extensions L workingy in said glands, and the spraying pipes extending from vthe pipes L along opposite sides ofthe machine, substantially as set forth.
